Title: Packing and unpacking publicVariable data
Post by: Mr.Peanut on 09 Sep 2008, 18:25:46

I am trying to make an enhanced publicvariable system in which each node has its own "channel", data may be sent from node to node, and a simple handshake verifies data delivery. As I plowed forward I suddenly realised "How the hell am I going to pack and unpack the data?"

Each node has a its own variable it monitors through a public event handler. Each "message" publicVariable'd through that variable has the form of an array:

Code: [Select]

[_tx, _datapack] where _tx is a header and

Code: [Select]

_datapack = []; {_datapack = _datapack + [[_x, call compile _x]]} forEach _data; where _data is an array of the variable names you want to PV.

How would I go about unpacking the data? Somehow I know:

Code: [Select]

{call compile (_x select 0) + " = " + str(_x select 1);} forEach _datapack;is garbage since the call compile _x used in data packing would, for objects, return local pointers not valid on the receiving machine. Help...  :blink:

The user has to give you the variable names and not the variable itself.

He is, but I am wrapping them.

How about:

Code: [Select]

{_tmp = _x select 1; call compile (_x select 0) + " = _tmp;";} forEach _datapack;

That should work.
